Patented June 6, 1939 I: [I HAM BOILER I Hans Beinwald, Ne wfYor lpplica tmn December 10,, 1 333, 3ml 8 7' H 3 Claims. (eras-22y .This:inventionrelates to ham boilers, that is, containers in which hams are adapted to be pressed and sealed, and aims to provide a ham boiler which may be readily used either for hand or machine pressing, and which at the same time embodies novel features and improvements such as, for instance, efficient restriction of the meat juices within the sealed'boiler.

The above and other objects will become apparent.in the description below,in which characters of reference refer to like-named parts in the accompanying drawings.

Referring briefly to the drawings, Figure 1 is a plan View of the boiler adapted for machine pressing.

Figure 2 is a cross-sectional view taken on the line 22 of Figure 1.

Figure 3 is a fragmentary end elevational view of the same.

Figure 4 is a cross-sectional view taken on the line 44 of Figure 2.

Figure 5 is a cross-sectional view taken .on the line 55 of Figure 2.

Figure 6 is a longitudinal cross-sectional elevational view of the boiler adapted for hand pressing.

Referring in detail to the drawings, the numeral I represents a vat-like container open at the top and provided in its upper peripheral edge with a groove I I. A press board I2 is adapted to slide vertically within the container I0 in the fashion of a piston in a cylinder, and is provided with a depending peripheral flange I3.

A sealing cover I4 has a peripheral depending bead I adapted to register in the groove I I, and intermediate its length has a pair of spaced vertical openings I6 therethrough. Raised flanges I'I surround the openings I6 on the top of the cover I4. A cross-beam I8 has at each end a recess I9 on its underside, in which the head of a stud 20 is pivotally suspended by a pin 2| extending at right angles to the beam I8. Each stud 20 is provided with a vertical row of serrations 22 on its outer side. These studs extend slidably through the openings I1 and at their lower extremities are pivotally secured at 23 to the board I2.

Between the opening I1 and the end of the cover, at each end of the latter, slots 24 are provided, which are open at the topand which extend into the openings IT. A sharpened or pointed tongue 25 is slidably mounted in the slot 24, and a spring 26 normally urges the tongue25 into the opening I I. The tongue is provided with an upward extending ear 21 which rises above the .iss acs i the spvmsp tna t fin e off-ins de ator may be readily applied thereto to move the tongue out of engagement with the serrated side of the stud 20. It is to be noted that the sharpened edge of the tongue 25 is at such an angle as to permit depression of the stud 20 through the opening I! but to prevent withdrawal upward of the stud, in the manner of the familiar ratchet and pawl.

Slotted extensions 28 are provided on the ends of the cover, adapted to receive the upper ends of screw bolts 29 pivoted at their lower ends on ears 30 on the end walls of the container I0. Wing screws 3| serve to clamp the cover tight against the container. 7

In using this form of ham boiler, the beam I8 is secured to the machine which presses the same downward, and the board I2 will remain locked in the lowermost position into which it is pressed. After the ham has been boiled, the board is released by withdrawing the tongues 25, and the cover is then removed in an obvious manner.

. When the ham is to be hand pressed in the boiler, the same container ID, the same press board I2, and the same cover I4a, may be used, although for the sake of simplicity the cover I4a shown in Figure 6 omits duplication of the showing' of the tongues 25, especially since the latter are not necessary for the construction shown. Other parts in Figure 6 which are identical to those of the other figures have been similarly numbered.

Instead of the beam I8 and its pivoted studs 20, a pair of mutually independent screw threaded studs 32 are threadably inserted into the openings I'I. It is to be noted that the latter are internally screw threaded in both covers I4 and Ma, although this fact was not heretofore mentioned because the threads in the cover I4 do not function as such.

The lower ends of the studs 32 are of a modified construction to permit rotation of the studs, as is obviously necessary. To accomplish this end, a nipple 33 is formed on the end of the stud 32 and provided with a peripheral groove 34. This nipple registers rotatably in a collar 35 having one or more set screws 36 passing through its side into engagement with the groove 34. The collar 35 is rigid on an ear 31 which is pivotally mounted at 23 on the board I2. The operation of this hand press form is obvious. Likewise, the changing of the boiler from a machine press to a hand press type or vice versa, is also apparent, and the changing over can be accomplished in a short interval of time.

3. A ham boiler comprising a container open at the top and having a press board vertically slidable therein, a cover having means for clamping the same on said container, said cover having spaced apart threaded openings therethrough, threaded studs passing through said openings, each of said studs having a nipple on its lower end and a collar rotatably surrounding said nipple, said nipples each having a peripheral groove, said collars each having set screws passing therethrough into said groove, said collars being pivotally secured to said board.
